Description

TECHNICAL FIELD OF THE INVENTION

The present invention generally relates to an ancillary device that generates a secondary fuel that is added into a primary fuel supply system of a vehicle to be supplied together to an engine cylinder so as to reduce the original consumption of fuel, enhance fuel combustion efficiency, and achieve an effect of energy saving and carbon reduction.

DESCRIPTION OF THE PRIOR ART

A conventional gasoline engine or diesel engine, when put into operation, emits exhaust gases, causing severe air pollution and leading to the global warming effect. In a combustion process of a diesel engine, various sorts of gaseous, liquid, and solid pollutants are generated and gaseous contaminants, such as carbon oxide (CO), sulfur oxides (SO_x), carbon dioxide (CO₂), and hydrocarbons (HC), are also generated, causing global ecological environment disruption issues, such as damaging the ozone layer, causing acidic rains, and increasing greenhouse effect and also causing potential healthy risks of human bodies. For example, nitrogen oxides may be converted into nitric acid, which causes acidic rains and damages the ozone layer and generates photochemical smog when acting with sun light. Particle pollutants or soot may contain polycyclic aromatic hydrocarbons (PAHs) or metal compounds that lead to pathological changes of lungs, tracheas, and respiratory tracts. Pollutants generated by a gasoline engine are not as much as those of the diesel engine, but there is still emission of toxicant substances, such as hydrocarbons, which may cause certain threat to human health and the environment.
Various solutions have been proposed in the motor vehicle industry. For example, a filtration system is included in an exhaust pipe of a vehicle engine to filter a mass emission of exhaust gases from the vehicle engine. However, this does not completely resolve the environmental protection issue that vehicles must consume a great deal of fossil fuel. As another example, electrical vehicles, hybrid vehicle, or solar vehicles are under development in the automobile industry; however, due to no significant breakthrough of the battery technology, problems such as storage capacity, charging speed, excessive weight of the battery have not yet been overcome. Thus, the costs of the electrical vehicles, hybrid vehicles, and solar vehicle remain very high, making it not possible for them to get popularized.
For the conventional diesel engines and gasoline engines, the consumption efficiency of fuel is around 15% to 28%. The incomplete combustion of fuel generates, almost every in the world, toxicant waste gases, such as soot (CO), suspension particles (PM2.5-PM10), hydrocarbons (HC), nitrogen oxides (NO_x), and bad smell gases. They affect the health of residents and also lead to warming of the Earth and abrupt change of climate.

SUMMARY OF THE INVENTION

An object of the present invention is to resolve the problem that the fuel combustion efficiency of an existing vehicle cannot be improved with a simple way so that the exhaust gases emitting after the combustion contains a high content of pollutant ingredients, making it easy to generate smokes and not allowing for reduction of fuel consumption.
The present invention is characterized in that a device that is mounted in an automobile to supply, in a proper manner, hydrogen and oxygen that serve as ancillary fuel. Hydrogen is supplied to a fuel pipe to be supplied with fuel into a combustion chamber of a cylinder of an engine for combustion and oxygen is supplied into an intake manifold for properly mixing with air to be supplied into the engine to support the combustion. By increasing the contents of oxygen and hydrogen in the fuel, at the moment of timed ignition, the mixed gas of hydrogen and oxygen and the fuel can be instantaneously and fast ignited so as to enhance the combustion efficiency of the fuel, improve driving power, and reduce all sorts of toxicant waste gases and bad smells, namely desired combustion performance and power being obtained through a reduced consumption of fuel, thereby accomplishing an effect of reducing the consumption of fuel and saving fuel costs.
A technical solution adopted in the present invention is that an electrolytic bath is mounted in an automobile to receive a supply of pure water. The electrolytic bath is electrically connected to an electrical power supply of the automobile. The electrolytic bath is connected to a first gas conveyance tube and a second gas conveyance tube. The second gas conveyance tube is connected to a fuel pipe of the automobile. When fed with an electrical current, the electrolytic bath electrolyzes the pure water supplied thereto into hydrogen and oxygen. The oxygen is supplied through the first gas conveyance tube into the intake manifold to be properly mixed with air for being introduced into a cylinder of the engine and the hydrogen is supplied through the second gas conveyance tube into the fuel pipe to be properly mixed with fuel and subsequently supplied with the fuel into the cylinder of the engine for combustion thereby achieving the purposes of saving energy and saving fuel and also accomplishing an effect of reducing contamination, eliminating bad smells, reducing carbon, and disinfection.
Another technical solution adopted in the present invention is that an electrolytic bath is connected to a first gas conveyance tube and a second gas conveyance tube. The first gas conveyance tube and the second gas conveyance tube are both connected to an intake manifold of an engine. After being fed with an electrical current, the electrolytic bath electrolyzes pure water into hydrogen and oxygen. The oxygen and the hydrogen are respectively supplied through the first gas conveyance tube and the second gas conveyance tube into the intake manifold to be properly mixed with air and then introduced into a cylinder of the engine for combustion.
The present invention is operable to continuously supply pure oxygen gas into the intake manifold to immediately and fast increase the oxygen content of the intake air and simultaneously reduce the nitrogen content of the intake air. The air with increased oxygen and decreased nitrogen, when introduced into the cylinder for combustion, can immediately increase the combustion efficiency of the engine and enhance power so as to achieve an effect of saving fuel and also help remove carbon deposit from the cylinder to thereby reduce the generation of soot and toxicant gases, such as PAHs, HC, and CO, resulting from incomplete combustion and contaminant suspension particles of PM2.5 and PM 10. Further, due to the reduction of nitrogen content, reduction of the formation of nitrogen oxides (NO_x) can also be achieved to protect the atmosphere from continuous damages caused by photochemical pollution.
While continuously supplying pure hydrogen gas into the fuel pipe, the present invention increases the hydrogen content of the fuel so that when fed into a cylinder for combustion, they increase the combustion efficiency of the engine and enhance power so as to achieve an effect of saving fuel and also help remove carbon deposit from the cylinder to thereby reduce the generation of soot and toxicant gases, such as PAHs, HC, and CO, resulting from incomplete combustion and contaminant suspension particles of PM2.5 and PM 10. Further, due to the reduction of nitrogen content, reduction of the formation of nitrogen oxides (NO_x) can also be achieved to protect the atmosphere from continuous damages caused by photochemical pollution.
The ancillary device of the present invention is controlled by an automobile computer so as to automatically activate or deactivate the electrolytic bath at the time when the electrical power supply of the automobile is turned on or off. The electrolytic bath, when activated, automatically regulates the voltage and the magnitude of direct current in order to control the rate of hydrogen and oxygen generated by electrolysis.
In performing electrolysis of pure water, the ancillary device of the present invention needs only to control, in a stable manner, the voltage and current in order to achieve control of the generation rate of hydrogen and oxygen for continuous feed into the fuel pipe and the intake manifold through negative pressure means (siphon effect). The hydrogen, after mixed with fuel, is supplied collectively into a combustion chamber of the engine to be ignited therein, while the oxygen is mixed with air in an intake manifold to be then supplied into the combustion chamber of the engine to support the combustion for achieving better combustion efficiency.
The present invention comprises throttle valves respectively mounted to the first gas conveyance tube and the second gas conveyance tube so that when the electrical power supply is shut down, the throttle valves are automatically closed to stop output of hydrogen and oxygen and when the electrical power supply is turned on, the throttle valves are automatically opened to output hydrogen and oxygen.
The present invention employs electrolysis of water to supply separate flows of pure hydrogen gas and pure oxygen gas to prevent, on the one hand, the generation of gas blowing and the risk of blow back when hydrogen and oxygen are mixed with equal ratio. Further, due to being combined with the electricity of an automobile, when the automobile is shut down, the operation of electrolysis stops simultaneously so that there is no risk resulting from storage of hydrogen or oxygen. Thus, the present invention can be regarded as a fuel-saving and pollution-eliminating device that is most economic, practical, safe, and effective.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.
